Anyone have a cropping/shearing machine and such a piece? It's small, 290x290mm, and 2.5-3.0mm thick is fine.
I can send a bundle of reinforced jiffy bags to put it in if it makes it easier to package it up & drop in a letter box.
It's to make an earthed quite-stiff base for 4x open frame PSU.
PS. If anyone wants M3x40mm M-F PCB standoffs, email as I have about 16 of them going cheap. Useful for many projects.
Thanks.
